...scure. "The mutant HD mice are unable to generate mature helper T cells, even though their immature T cells carry the CD4 protein," Kappes explained. "Instead, the mutation redirects them to the killer-cell pathway. "Our new study identifies this defect as a point mutation in the zinc finger transcription...

.... The protein is known as mBDNF, which stands for mature brain-derived neurotrophic factor. In an earlier study, another team of NICHD researchers had shown that mBDNF is essential for the formation of long-term memory, the ability to remember things for longer than a day. “Understanding how BDNF is made ...

...id of defective cells before they have a chance to mature and divide. When tumor suppressor genes lose that ability ?as they can if they are silenced through methylation or some other process, it gives cancer a chance to establish a foothold and spread. Caligiuri says much more work needs to be done, but a...

...omes a moving cloud of contagions. Sea lice larvae mature and reproduce on the seaward salmon with each louse producing 300-800 eggs. This second round of lice larvae can re-infect the fish in the school and can spread to other previously unexposed populations coming from geographically disparate regions. ...

...is characterized by theprogressive accumulation of mature B lymphocytes in the blood, bonemarrow, and lymphatic tissues. It is believed that in the early stagesof disease, B-CLL is the result of an undefined defect in theprogrammed signals that trigger normal B cell death (apoptosis). LivioTrentin and colle...

...ntrast, B cells, which make antibodies, remain and mature in the bone marrow. Until now, scientists thought NK cells did the same. But Caligiuri, working with Aharon Freud, the lead author of the study and a doctoral candidate in Caligiuri's laboratory, had noted other work showing that mice lacking lymph ...

...egetable consumption that often occurs as children mature into adulthood. This is definitely an area that merits more research." The bitter receptor genotype also predicted children's sweet preference, along with their preference for sweet-tasting beverages and foods. Children with a bitter-sensitive allel...

...years ago, when the hydrocarbon deposits were less mature and closer to the surface of the earth. Luca scientists, employing the tools of modern biotechnology and genomics, have now shown that living methane generating, microbial consortia are present and actively forming methane within some of these hydro...

...mal papilla, and both structures contribute to the mature hair follicle. During development, cells are constantly bombarded with external signals. The trick is figuring out which signals trigger the transcriptional and behavioral properties in cells that spur bud formation. In previous experiments, Fuchs a...

...o patterns that become the various body parts of a mature organism. In fruit fly embryos, for example, the first cells are thought to differentiate into the head, abdomen and other parts based on the concentration of chemical signals that are emitted from the ends of the embryo. In addition to conducting l...

...s these blood cells develop, the gene protects the mature cell against HIV infection. The UCLA AIDS Institute already has completed a Phase I clinical trial using adult stem cells. Embryonic stem cells also could be engineered for this strategy to avoid the need for isolating patients' cells, ease transplan...

...quence that they knew might prod the stem cells to mature into insulin-producing cells. After some trial and error, they found the right combination and sequence. The end result was a dish full of cells that could produce insulin and release it in response to sugar added to the environment. These cells don...

...d immune cells in the transplanted mice, but their mature B lymphocytes were defective. Without IRE1, lymphocytes don't develop a B cell receptor and don't have the right rearrangements of immunoglobulin genes to function properly. "Our findings show that IRE1 is required for both the early and late stages...

...sible to study the role of the gene of interest in mature animals. Dr. Michael P. Cooke and colleagues from the Genomics Institute of the Novartis Research Foundation in San Diego found a way around this problem. The researchers used random mutagenesis and screening to find animals with hematopoiesis defec...

...cal procedure. Finally, cord blood cells are less mature than adult bone marrow cells and thus do not need to perfectly match the patient's immune-related blood proteins, called antigens, said Kurtzberg. Only four of six cord blood "antigens" must match for a transplant to have a reasonable chance of succe...
